Influences of Friction stir tool parameters for joining two similar AZ61A alloy plates

Multi-criteria optimization on friction stir welding of aluminum composite (AA5052-H32/B4C) using titanium nitride coated tool

“…To avoid investigational blunders, experiments for tensile strength, microhardness, and percentage of tool wear loss were replicated two times [27]. These values are greater than 95% of the confidence interval [28]. The formulae for the 'higher and lower-the better' rules of signal-to-noise (SN) ratio are shown in equations (2) and (3), respectively.…”

An Analytic Hierarchy Process for a General Ranking of Friction Stir Welding Parameters Optimized Through the Design of Experimental Arrays

“…Literature overviews of the optimization of FSW parameters for aluminum and its alloys , magnesium alloys [47][48][49][50][51][52] , steel and its alloys [53,54] , copper and its alloys (i.e., brass) [55,56] , dissimilar joints of aluminum to copper and their alloys [57][58][59][60][61][62][63][64][65] , aluminum alloys to steel alloys [66][67][68][69][70][71][72] , aluminum alloys to magnesium alloys [73] , and steel alloys to copper [74] are provided in Tables 1-8. It demonstrates the selected parameters in their optimization studies, percentage 3/20 https://www.doi.org/10.53964/jmim.2022005 of contributions % obtained, arrays used, alloys, thicknesses of materials, statistical DOE methods performed, and the efficiencies of responses (properties) acquired in these investigations.…”

“…Solid-state techniques such as FSW are available to overcome various flaws related to fusion processes, such as hot cracking, distortion, and porosity. FSW performs under the melting temperature, about 10-20%, of the materials [1] and has been vastly utilized for welding similar or dissimilar metals for aluminum and its alloys , titanium alloys [46] , magnesium alloys [47][48][49][50][51][52] , steel and its alloys [53,54] , copper and its alloys (i.e., brass) [55,56] , dissimilar joints of aluminum to copper or brass [57][58][59][60][61][62][63][64][65] , aluminum to steel [66][67][68][69][70][71][72] , aluminum to magnesium [73] , and steel to copper [74] . These metals are regarded as hard to weld by traditional fusion processes.…”

“…This study firstly ranked the parameters separately of each metal joining group based on the types of metals. Eight sets were selected, namely aluminum and its alloys , magnesium alloys [47][48][49][50][51][52] , steel and its alloys [53,54] , copper and its alloys (i.e., brass) [55,56] , dissimilar joints of aluminum to copper and their alloys [57][58][59][60][61][62][63][64][65] , aluminum alloys to steel alloys [66][67][68][69][70][71][72] , aluminum alloys to magnesium alloys [73] , and steel alloys to copper [74] . Each metal group had different combinations of optimized parameters.…”

Optimization of Process Parameters of Composite Wicked Heat Pipe

“…The utilization of nano liquid as working liquid cause's slender sedimentation on screen work wick covering diminishes pore size of work which could influence fine execution. Xianming Dai [8,21] et al 2011 did characterization of Hybrid mischievous copper heat pipe .A tale scale crossover wick was created in this examination to improve compelling thermal conductivity heat transition of level heat pipes. Experimental results show that powerful thermal conductivity can move toward 12,270 w/m k which in excess multiple times superior to unadulterated copper at application 91.3 heat input.…”
